IPC: A61P37/04
Filed: 2002-04-02
Granted: 2014-01-21
Abstract: La présente invention porte sur une composition comprenant un peptide immunogène utile pour la prévention et le traitement de la maladie d'Alzheimer. Plus particulièrement, le peptide immunogène comprend un site principal fonctionnel/régulateur, un fragment N-terminal d'un peptide amyloïde.beta.(A.beta.) lié un épitope de lymphocyte T auxiliaire (Th) ayant de multiples motifs de liaison de CMH de classe II. Ce peptide immunogène provoque une réponse immunitaire dirigée contre le site principal fonctionnel/régulateur du peptide A.beta et génère des anticorps qui réagissent fortement de façon croisée avec le peptide A.beta 1-42 et les plaques amyloïdes formées dans le cerveau des patients atteints de la maladie d'Alzheimer. Les anticorps générés étant susceptibles de réagir de façon croisée le peptide A.beta 1-42 soluble, ils entraînent la désagrégation de fibrilles et inhibent l'agrégation de fibrilles menant à l'immunoneutralisation des « toxines dérivées des A.beta solubles » et, du fait qu'ils peuvent réagir de façon croisée avec les plaques amyloïdes, ils accélèrent la disparition de ces plaques dans le cerveau. Ainsi, la composition de l'invention comprenant ce peptide immunogène est utile pour la prévention et le traitement de la maladie d'Alzheimer.
